Definitions

  • the present disclosure relates to the technical field of exhaust supercharging of diesel engines, and in particular, to a pulse exhaust pipe for a diesel engine.
  • Exhaust pipes for eight-cylinder matched double-supercharger engines in the prior art mainly include a common pulse exhaust pipe as shown in FIG. 1 and a three-cylinder pulse exhaust pipe as shown in FIG. 2 .
  • the common pulse exhaust pipe is relatively high in pumping loss and relatively high in fuel consumption rate due to the ignition order.
  • the pulse energy utilization rate is increased and the pumping loss is reduced by improving the common pulse exhaust pipe, the three-cylinder pulse exhaust pipe in the prior art is provided, and a connected structure of the three-cylinder pulse exhaust pipe is shown in FIG. 2 .
  • the three-cylinder pulse exhaust pipe is prone to backflow of exhaust gas and backflow of intake air, so the uniformity of each cylinder is relatively low. If the phenomenon of the backflow of exhaust gas occurs in the exhaust pipe, the pulse energy utilization rate is relatively low, and the uniformity of each cylinder needs to be improved.
  • an ignition interval angle between the various cylinders shall be smaller than an exhaust duration angle.
  • the exhaust pipe is divided into several mutually separated exhaust pipe sections such that adjacent cylinders discharge to a supercharger through different exhaust pipe sections, i.e. different exhaust passages.
  • the exhaust phases of the respective cylinders connected to each exhaust pipe section must not be superposed or are superposed a little.
  • the opening duration angle of its exhaust valve approximately corresponds to a stroke from a cam angle of 240 degrees to a cam angle of 280 degrees.
  • the number of cylinders connected to each exhaust pipe section is generally not more than three, and the exhaust phases of the three cylinders must be uniformly staggered.
  • an exhaust interval angle of two cylinders discharging to the same exhaust pipe section is equal to or greater than the exhaust duration angle of one of the cylinders, that is, after the exhaust valve of the previous cylinder is closed, the next cylinder then discharges to the exhaust pipe section.
  • the exhaust interval angle of the multi-cylinder engine is decreased as the number of cylinders increases, so that the structure is too complicated because of the increased number of exhaust pipe sections on the multi-cylinder engine.
  • an exhaust interruption may occur in the exhaust pipe, which reduces the efficiency of a turbine.
  • the exhaust pipe used also needs to avoid the occurrence of the backflow of the exhaust gas.
  • the present disclosure applies a 16-cylinder V-shaped engine equipped with four superchargers.
  • the cylinders are sorted as shown in FIG. 3 .
  • the ignition order is A1-A7-B4-B6-A4-B8-A2-A8-B3-B5-A3-A5-B2-A6-B1-B7, and the ignition interval angle is 45 degrees.
  • the three-cylinder pulse exhaust pipe compared to the common exhaust pipe has the advantages that the utilization rate of exhaust pulse energy is higher, the pumping loss is reduced, the charge efficiency is improved, and the fuel consumption is reduced.
  • the phenomena of the backflow of exhaust gas and the backflow of intake air occur in the second and sixth cylinders.
  • the exhaust interval angle of the two cylinders A6 and A7 is 180 degrees
  • the exhaust interval angle of the two cylinders A2 and A3 is also 180 degrees.
  • the third and seventh cylinders just discharge, and then the exhaust gas of the second and sixth cylinders flow back, which causes the pressure in the cylinder to be greater than the pressure of an air inlet when an air inlet valve is opened and results in the backflow of the intake air.
  • the objective of the present disclosure is to solve the following technical problems by discussing what kind of pulse exhaust pipes adopted by an eight-cylinder matched double-supercharger engine may optimize the reliability, the economy and the manufacturability of the engine, that is, by discussing how to effective make use of exhaust pulse energy to reduce the exhaust pumping loss, achieve the aim of reducing the fuel consumption and also avoid backflow of exhaust gas and backflow of intake air due to a relatively short ignition interval of adjacent cylinders, thereby increasing the charge efficiency of the engine, improving the uniformity of each cylinder and the uniformity of an exhaust temperature distribution, reducing deformation or cracking caused by non-uniform distribution of stress on a partition at an outlet of the exhaust pipe and improving the reliability of the exhaust pipe.
  • the objective of the present disclosure is achieved by the following technical solution.
  • the present disclosure provides a pulse exhaust pipe for a diesel engine.

  • the first exhaust pipe section is communicated with the first and second cylinders.
  • the second exhaust pipe section is communicated with the third to sixth cylinders.
  • the third exhaust pipe section is communicated with the seventh and eighth cylinders.
